Titanium Oxide Coated Filter (TiO2)
The TiO2 Filter works in cooperation with UV light rays to destroy VOCs; converting 95% of pollutants in the air to harmless water vapors, leaving your home smelling fresh and clean.

There's no need to clean the TiO2 Filter, because when the UV-C light hits the filter, it will release oxidizes into the air which will remove contaminates, odors, etc. Under normal conditions the TiO2 Filter should be replaced every 2 years.
